Windows Defender is a great antivirus program, but it's lacking something important... FREE WINDFORE. The free version only comes with the Windows Registry Engine and Network Diagnostic Tools, which are the programs that help you fix your computer in the event of a problem. It's also pretty basic in terms of user support. That's why I'm going to show you how to download a FREE version of WinDock from ITunes. First, to get started, you have to make a user profile or chose a user profile from your default ones.
To make a new user profile, what you have to do is just click on the Add button and then select Windows Registry Engine from the drop-down menu. Now, click Next to continue. In the Registry Editor, there will be a pane for Windows components. Under components, you'll see an item called WinDock. You'll want to double-click on it. Then, you'll see a window popup with some basic information about your computer, including the Path option which specifies the program you're trying to run.
Once you click OK, you can see your new windows icon on your desktop. This shows you that you've successfully moved windows and your system will restart normally. If your problem is related to missing files, this tool can help you find them. It even has a "restore" option to get you running as fast as possible!
